Spin dynamics of electrons, holes, and excitons in lead-halide perovskite semiconductors
relaxation mechanisms [2,3,4]. Exciton spin polarization at cryogenic temperatures in bulk perovskite crystals with near-cubic (FA₀.₉Cs₀.₁PbI₂.₈Br₀.₂, FAPbBr₃) and orthorhombic (MAPbI₃, CsPbBr₃) symmetries has [...] and efficient spin initialization under circularly polarized excitation [2,3,5]. Spatial confinement of excitons in CsPbI₃ nanocrystals leads to a regime in which spin properties are governed primarily [...] spin dynamics. At the same time, spatial confinement of both excitons and acoustic phonons in CsPbI₃ nanocrystals results in significant enhancement of exciton–phonon interaction. This makes it possible …
